A blogger who called a local politician a 'c***' on Twitter sparked a row over freedom of speech after being convicted of sending the offensive remark.

John Graham Kerlan who blogs under the name Olly Cromwell, faces jail after Councillor Melvyn Seymour complained.

Kerlan, who was attacking Bexley Council in south east London, posted an image of Mr Seymour's house, as well as a tweet saying: 'Which c*** lives in a house like this. Answers on a postcard to #bexleycouncil.'
